摘　　要：目的探讨视觉诱发电位(VEP)在轻型视神经损伤患者视功能检查中的应用价值。方法对25例面部或眼部外伤患者外伤后48 h内行VEP检查,以对侧眼作为对照,观察P100潜伏期及振幅。结果患眼VEP中P100潜伏期较对侧眼无明显延迟,P100振幅较对侧眼降低。结论 VEP检查对轻型视神经损伤的早期诊断及治疗有重要意义。Objective To evaluate the role of visual evoked potential （VEP） in the evaluation of slight traumatic optic neuropathy. Methods VEP exami- nation was conducted in 25 patients （25eyes） with ocular contusion and facial injuries within 48 hours after injury, and the healthy eyes were taken as con- trols. The P100 latency and amplitude were ob- served. Results There was a significant reduction in P100 amplitude in injured eyes compared with healthy eyes, but there was no obvious delay in P100 latency. Conclusion VEP plays an important role in the early diagnosis and treatment of slight traumat- ic optic neuropathy.
